How much oil does the AC system take and where do you put it in at? I just replaced all the lines on my 2001 Ram 2500 and I have a buddy who will pull a vacuum and charge it for free I just have to add oil.

 

Should be in the service manual.... I think it even tells ya where to put it..... (hhmmm.... that just doesn't sound right....... )

 

It says 6.25 but not where to put it lol I know there is still some in it but I'm going to try and charge it and see what happens lol

 

Well charged it had AC for three seconds turns out the condenser is leaking lol

 

From what I have seen, folks put a bit in the compressor, some in the accumulator, and even some in the condenser....... Don't wanna put it all in the compressor, as you don't want to hydro-lock it, and destroy it.

 

Put it in the receiver/dryer.

 

When I install the new (used) condenser I will add some oil to it. This is just a trial run. If the compressor blows it blows and I'll have the system evacuated, vacuum pulled, and recharged with the right amount of oil and freon. To do all that a garage wants $350 and that's the cheapest I found.

 

I don't like to reuse old receiver/dryers from a junk yard. I'll reuse one when I open then pump down a system right away. The dryer can only hold about a tablespoon of moisture. I put most of the PAG oil in the compressor, a little in the condenser and dribble a little into the lines.

 

I replaced all the lines and dryer yesterday (new from Rockauto) so they is what is driving me to get the AC working lol

 

If you're like me (and I know I am) I'd want to get it working and not worry about it. When I fixed my Escalade a couple of years ago, I went ahead and replaced the compressor too. That way you don't have an old one fail and dump a bunch of metal junk in the system you have to clean out. I'd even go so far as to replace the serpentine belt if it's got much age on it.
